This Blueberry Mocktail is sweet and sour with the perfect combination of flavor and color to make it almost as appetizing to look at as it is to drink. This take on a whiskey smash is easy to make and provides depth of flavor where that can sometimes be missing in a mocktail.

The Bite of a Cocktail in a Mocktail

The one thing I need in a mocktail is a little "bite" or sourness. I can't just have a sweet drink. I don't have any interest in a mocktail that tastes like sweet juice. I love that this blueberry mocktail has the sour forward flavor that makes it feel like an adult beverage.

I don't mean to say that it tastes like alcohol - I just mean that it feels like an adult drink. Like my kid probably wouldn't want to drink it. And you can bet your ass I'm not muddling berries for that little terror.

If you served it at a party, it would feel elevated and not like you're serving blueberry juice to everyone. I like to think of this cocktail as a Blueberry Smash Mocktail - sort of like a Whiskey Smash.

Ingredient Notes and Substitutions

Seltzer. When I make mocktails, I've found that using a flavored seltzer can add in a little of that flavor that's lost if you're looking for that "cocktail" flavor. This Blueberry Pomegranate one complemented the drink perfectly.
Agave. The agave gives the drink a little bit of froth when shaken. You can substitute simple syrup for the same flavor and effect.
Blueberries. The sweeter and more flavorful the better. If it's not blueberry season, frozen blueberries work really well!
Thyme. Thyme adds a subtle flavor and aroma I find goes really well with this drink. Rosemary could be a good substitute.
Lemon. The acidity of the lemon balances the drink out from the sweetness of the blueberries.

How to make a Blueberry Mocktail

Step 1: Add blueberries, lemon juice, and thyme, removed from stem, to a cocktail strainer. Use a muddler to muddle the blueberries into a pulp.

Step 2: Add ice and agave and shake vigorously.

Step 3: Pour the seltzer into the shaker and stir well. Strain the drink into a martini glass to serve up. Garnish with a sprig of thyme as shown below.

This drink is great for the evening and it can be served with appetizers like Steamed Mussels in White WineorVeggie Stromboli.

Pro-Tips

Roll the lemon on a cutting board to loosen up the juice before you cut it open to squeeze in.
Thaw the blueberries in the refrigerator overnight if using frozen blueberries.

Recipe FAQs

What alcohol can I add to this drink?

Whiskey goes great in a smash cocktail like this. I tried it both with and without whiskey and it is flavorful and delicious with or without.

What if my blueberries aren't sweet?

If you know that it's not blueberry season and your berries won't be sweet, definitely substitute frozen berries. Thaw them the night before or even a couple hours before. Frozen berries are almost always sweet.

Do I need to use a flavored seltzer?

You don't need to use a flavored seltzer, but I like to in a mocktail. A plain seltzer with no flavor is fine with an alcoholic beverage, but I like the extra kick of a flavor this Blueberry Pomegranate seltzer gave this drink!
